Here's what I've found within 200 miles on Craigslist:
John Deere 455 - $2,200
Cub Cadet 2166 - $850
Cub Cadet 2160 - $650
Honda 3813 - $800
Honda 4515 - $800
Comments, please? Do any of these seem particularly better or worse?
I have sent questions about them (hours, issues, etc.), but I haven't received any replies yet.
Thanks!
First, when looking at used mowers, tractor data is your best friend
http://www.tractordata.com/
Of the 4 you have found to date,
The JD is the only one that still has factory support, it will be the most expensive to repair but it should give many years of good service.
The pollycarbonate outer bodies get brittle & break off the mounting tabs but they are cosmetic only so you can run without them bit that makes them hard to sell.
The price is good
The Cubs will be the easiest to repair, they were commercial mowers in their day.
The electrics are a PIA to repair and are the weakest part of the tractor.
I have a lot of them in my service run.
The shaft drive is excellent the std blades will chop trees and the deck is the easiest to remove.
MTD adopted the Cub deck mount across it's entire range after they purchased Cub ( think it was the only reason why they bought Cub ).
The decks are the lightest & I weld reo bar around the front to strengthen them as my customers continually drive the decks into star pickets. bit rocks tree stumps etc which bends the deck back & fouls on the blades.
The Hondas will be the least likely to require repair, they are tough & bullet proof .
They have a much stronger deck that the Cubs ( and heavier ) blades are not as tough but there is a Gator replacement.
The only down side is mower parts, some of which ( throttle lever ) are NLA but if you are happy & handy with making a wrong parts fit, they will serve you well.
The water cooled engines have a very long life
